Problems solved by technology

This patent is to introduce α-alumina single crystal and zirconia single crystal into the traditional tire raw materials to enhance the strength of porcelain to achieve the purpose of firing thin tires, but several toughening materials in this patent document are barren materials , too much content will directly affect the plasticity of the blank, which is not conducive to the molding of thin body reinforced porcelain, resulting in a low yield, which is not conducive to the conventional production of daily-use porcelain

Abstract

The invention discloses a high-aluminum egg-shell reinforced celadon and a preparation method thereof. The high-aluminum egg-shell reinforced celadon is prepared from a high-aluminum egg-shell reinforced celadon blank and high-aluminum egg-shell reinforced celadon green glaze. The high-aluminum egg-shell reinforced celadon blank is prepared from high-aluminum egg-shell reinforced celadon slurry. The high-aluminum egg-shell reinforced celadon slurry comprises, by weight, 25-35% of Baoxi porcelain clay, 13-23% of Zhuxiang porcelain clay, 25-35% of Yuandi porcelain clay, 20-35% of alpha-Al2O3 micro-powder, 2-4% of zirconia micro-powder and 0.5-2% of PVA. The celadon green glaze comprises, by weight, 30-45% of Huangshixuan glaze clay, 20-30% of Xiyuan glaze clay, 15-25% of limestone, 4-8% of quartz and 10-20% of potassium feldspar. Through use of a proper amount of alpha-Al2O3 micro-powder and zirconia micro-powder as toughening materials in blank materials and use of PVA as a plastic adjusting agent, blank strength is improved and the clay has a certain plasticity and daily use ceramic production requirements are satisfied.

Description

technical field [0001] The invention belongs to the technical field of porcelain preparation, and in particular relates to a high-aluminum thin-bodied reinforced celadon and a preparation method thereof. Background technique [0002] Celadon is a kind of porcelain with cyan glaze on the surface. It is a treasure of Han ceramic firing technology. The color tone of celadon is mainly caused by a certain amount of iron oxide contained in the glaze, which is baked in a reducing flame atmosphere. However, some celadon porcelains are yellow or yellowish-brown due to the impure iron content and insufficient reducing atmosphere. [0003] Longquan City, Zhejiang Province is a famous capital of celadon in my country. It is rich in porcelain clay mineral resources, and the local area is rich in high-silicon and high-iron porcelain clay. Longquan celadon is a famous porcelain variety in my country, and it is also the only ceramic project in China that has been selected into the represen...
